The use of optical coherence tomography (OCT) is expanding into previously uncharted territory: the choroid. As researchers fine-tune enhanced depth imaging OCT, ophthalmologists are gaining a new tool to evaluate choroidal conditions, retinal degeneration and ocular tumors.

A $2 million grant will help Cole Eye Institute scientists produce a three-dimensional model of an individual patient’s corneal shape and material strength. The model would help identify early signs of keratoconus, and would serve as a ‘virtual eye’ to test treatments or screen refractive surgery candidates.

Cole Eye Institute ophthalmologists are seeking to understand how an enhanced retinal imaging technology, known as ultra-widefield imaging, can clarify how to best manage patients based on the degree of ischemic burden.

Bacteria aren’t the only microbes that cause corneal infections. The protozoa Acanthamoeba, which can be introduced to the eye via contact lenses, is a rare, vision-threatening form of keratitis requiring careful diagnosis.

For the right patients, the corneal transplant procedure known as Descemet’s stripping automated endothelial keratoplasty (DSAEK), allows quick recovery of normal vision and less risk of rejection and other complications.
